<div>
<pre>`throw expr;` is not assumed to never return.
This results in *much* worse codegen, which can be seen by substituting
<span class="quote">> { throw expr; import gcc.builtins; __builtin_unreachable(); }</span >
for
<span class="quote">> throw expr;</span >
That is not a perfect workaround, as the compiler then warns
about that `builtin_unreachable()` statement being unreachable
(but at least does the right thing and eliminates the unreachable
paths). Using `assert(0)` works, but adds unnecessary bloat (the
dead trap code in release mode).</pre>
